Sunlight‐Driven Green Synthesis of Platinum Nanoparticles From Double‐Vacancy Halide Perovskite Precursors for Methanol Reforming

open access: yesChemistry – A European Journal, Volume 32, Issue 32, 24 August 2026.
Sunlight‐driven synthesis offers a green and energy‐efficient route to metallic nanoparticles. Here, double‐vacancy halide perovskites (Cs2PtX6, X = Cl, Br) act as photoactive precursors for the in‐situ formation of ultrasmall (< 3 nm) platinum nanoparticles under simulated sunlight at room temperature.

Use of Invasive Rugulopteryx okamurae Beach Wrack as Habitat and Food by Talitrus saltator

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 8, August 2026.
ABSTRACT The introduction of non‐native algae into coastal waters has increased worldwide, causing a range of ecological and socio‐economic impacts. However, when stranded on beaches as wrack, these invasive algae can provide refuge and food for supralittoral organisms, potentially benefiting local fauna communities and beach functioning. In this study,

Artificial exposure to herbivore‐induced volatile organic compounds reduces herbivory and modulates gene expression in potato plants

open access: yesJournal of Applied Ecology, Volume 63, Issue 8, August 2026.
These findings provide strong mechanistic evidence for VOCs mediating pest resistance and suggest that exposure to herbivore‐induced, plant‐derived VOCs can enhance pest resistance in potato crops. These results might offer novel information for developing ecologically sustainable plant volatile‐based strategies for boosting protection against pests in
